Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut ...
Liquefied chlorine is transported for eventual solution in water, after which it is used for water purification, sanitation of industrial waste, sewage and swimming pools, bleaching of pulp and textiles and manufacture of carbon tetrachloride, glycol and numerous other organic compounds as well as phosgene gas.
Diphosgene converts to phosgene upon heating or upon catalysis with charcoal. It is thus useful for reactions traditionally relying on phosgene. For example, it convert amines into isocyanates, secondary amines into carbamoyl chlorides, carboxylic acids into acid chlorides, and formamides into isocyanides. Diphosgene serves as a source of two ...
Such compounds are potent alkylating agents, making mustard gas acutely and severely toxic. [3] Mustard gas is a carcinogen . [ 3 ] There is no preventative agent against mustard gas, with protection depending entirely on skin and airways protection, and no antidote exists for mustard poisoning.
It behaves like phosgene, to which it cracks thermally: OC(OCCl 3) 2 ⇌ 3 OCCl 2. Alcohols are converted to carbonates. Primary and secondary amines are converted to ureas and isocyanates. [6] [7] [9] [10] Triphosgene has been used to synthesize chlorides. [8] Some Alkyl chlorides are prepared by treating alcohols with a mixture of triphosgene ...
Phosgene is considered safe at 0.1 parts per million during an eight-hour exposure, or 0.2 ppm for a 15-minute exposure. The eight-hour exposure threshold would have to be even lower when ...
The daily Svenska Dagbladet newspaper said authorities had found traces of phosgene. The gas has a strong odor that can cause vomiting and breathing trouble and was used as a weapon in World War I.
“It’s so rich,” Canal says in the video. “Like Tom Cruise.” The pastry is so famous, it was immortalized in HBO comedy series “Hacks.”In the Season 3 premiere, fictional superstar ...
